Piezoelectric Gong

If we made a very large Gong and coated it with Piezoelectric Crystals would the Gongs frequency when struck be sufficient to stress the Piezoelectric properties into giving up electrons to discharge an electric spark?

If so, Would making the Gong from LiquidMetal lengthen the time the Gong resonates the Crystals?, See: LiquidMetal

It wouldn't have anything to do with the frequency, only the amount of strain imposed on the crystals. However, the strain on the crystals accross the gong would not be uniform.

Also, it would create a high frequency alternating voltage because the strain on the crystals would be sinusoidally changing.
